Guy Fieri

Guy Fieri has a well-documented hatred of eggs that stems from a childhood experience learning where chickens come from. On a "Diners, Drive-Ins and Dives" episode, he got queasy when someone cut into a yolk on top of a pizza.

Andrew Zimmern

Even though he's adventurous AF on "Bizarre Foods," there are a few pretty standard foods Zimmern is NOT a fan of: walnuts, raw cookie dough, and oatmeal. "Won't eat em, can't stand em," he told PEOPLE.

Ree Drummond

The Pioneer Women made her stance on one fruit very clear in a blog post that was ironically about bananas foster. "I hate, abhor, loathe, and recoil at the sight of bananas," Drummond wrote. "I've disliked them my entire life, even when I was a baby."

Anthony Bourdain

For Bourdain, it's not so much a specific food as a whole category: plane food. He prefers to arrive at a destination hungry, and as he told to Bon Appétit, "No one has ever felt better after eating plane food."

Alton Brown

Truffle had a definite moment not too long ago, popping up on burgers, fries, pizzas, and more. Alton Brown doesn't buy it. He told Grub Street that "truffle oil sucks," and wrote on Twitter that it "ain't go no reason."

Gordon Ramsay

Gordon Ramsay's disdain for pineapple pizza is as well-documented as his love for Twitter rants. Besides tweeting about it o n several occasions, he stated loud and clear on "The Nightly Show" that "you don't put f---ing pineapple on pizza."
